Evergreen content refers to any type of content that remains relevant, accurate and useful long past its publication date. To be considered evergreen, content must be written on a topic that doesn’t change drastically from year to year, contain knowledge that’s foundational to a realm of study or skill, be perpetually useful, accurate and relevant, and have minor outdated facts or references that can be easily updated. Evergreen content is essential for search engine optimization as it is reliable and sustainable, and generates a steady influx of potential customers. Types of evergreen content include ‘how-to’ content, listicles, and informational content such as beginner guides. To ensure that content is evergreen, it’s important to avoid references to cultural events, news or trends that will quickly become dated, and only link to trusted sources. Examples of evergreen content include Yoast SEO’s blog post on transition words, a DIY wooden backyard fence tutorial, a beginner’s guide to investing in stocks by Investopedia, an extensive guide to making pie dough, and a HubSpot blog on cybersecurity. To write evergreen content, it’s important to keep examples, asides, and jokes timeless, and only link to sources that will stand the test of time.
